The  sign was added in GC probably by Chopin. GE extended it, so it filled both bars, in this version it was added also in EE2.

In FE there are no flats restoring g and g1 on the 5th quaver. As respective signs are before the 9th quaver (in all sources), the version, with g and g1 on the 5th quaver, formally does not contain a mistake. In spite of this, it seems to be much more likely that it is a mistake that happened to Chopin in [A] – in GC (→GE) the composer added the overlooked flats, the signs were also added in EE and FED, which, in both cases, may come from Chopin. Therefore, we are dealing with a too late placement of sign, which is not an isolated case – cf., e.g., the Etude in F major, Op. 10 No. 8, bar 43. In the main text, we do not include the superfluous flats in the 2nd half of the bar.

b. 59

..

Chopin added the cautionary flats before c-c1 in GC (→GE). They were added – most probably on the basis of GE – also in EE2.
